The broader impact/commercial potential of this I-Corps project is in the development and validation of a minimally invasive blood test that can help assess cancer patients' response earlier and more accurately than current standards of care such as computerized tomography (CT) scans and antigen testing. The results from current tools often leave patients and physicians waiting for extended periods and can lead to ineffective therapies and downstream diagnostic follow-ups. This technology provides real-time insights into how a patient is responding, thus informing clinical decision-making and improving patient outcomes. There are currently 16 million cancer survivors in the US, and the uncertainty of relapse causes significant anguish for patients and caregivers alike. This technology addresses cancer types ranging from colorectal cancer to glioblastoma, and from breast cancer to lung cancer.This I-Corps project develops novel methods for detecting and quantifying methylation, structural patterns in patients' blood. Current approaches for detecting methylation involve a harsh chemical modification that degrades almost 90% of the DNA and limits the overall accuracy. The approach used here has demonstrated initial success with the use of bisulfite-free approaches to detect and quantify methylation patterns. This workflow includes the use of a novel methylation-sensitive fusion protein and a nanomaterial platform to amplify the signal. The proposed technology has the potential to detect methylation signals at multiple timepoints within the patient care journey and to create significant clinical impact.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

I-Corps项目更广泛的影响/商业潜力在于开发和验证一种微创血液检查，这种检查可以比目前的护理标准（如计算机断层扫描（CT）扫描和抗原检测）更早、更准确地评估癌症患者的反应。现有工具的结果往往使患者和医生等待较长时间，并可能导致无效的治疗和下游诊断随访。这项技术可以实时了解患者的反应，从而为临床决策提供信息，改善患者的治疗效果。目前，美国有1600万癌症幸存者，复发的不确定性给患者和护理人员带来了巨大的痛苦。这项技术适用于从结直肠癌到胶质母细胞瘤，从乳腺癌到肺癌的癌症类型。这个I-Corps项目开发了检测和量化患者血液中甲基化结构模式的新方法。目前检测甲基化的方法涉及一种苛刻的化学修饰，这种修饰会降解几乎90%的DNA，并限制了整体的准确性。这里使用的方法已经证明了初步的成功，使用亚硫酸氢盐的方法来检测和量化甲基化模式。该工作流程包括使用一种新型甲基化敏感融合蛋白和纳米材料平台来放大信号。所提出的技术有可能在患者护理过程中的多个时间点检测甲基化信号，并产生重大的临床影响。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
